This kind of behavior we typically see if some elog entry is corrupt. After a few hours you might access this corrupt entry by accident, and then the
server stops. If you see however this behavior on a fresh logbook with no corrupt entries, then the problem must lie somewhere else.
Do you see the same problem running under linux? |

Thanks for the prompt feedback.
a) I confirm that the problems shows up also when running interactively the elog through elogd -p 8080

What you recommend is enough. Just make sure to compile elogd with the flags mentioned before, and when you get the segment violation, do a stack trace

It seems that it has something to do with the 'first' logbook that contains 115 entries and is displayed in 6 pages. |

Actually it is a little bit more difficult than that.
I have restarted elogd and got a crash but this time it seems related to a different logbook...

Ok, that helped. It looks to me that the strlcpy() function from MacOSC does not like overlapping stings as parameters. Funny that this does not happen
on my Mac (Mojave 10.14.4). I fixed the two cases you reported (lines 18712 and 19021) and committed the changes to bitbucket, from where you can pull
and test it again (see https://elog.psi.ch/elog/download.html for instructions). If it happens |

Thanks a lot for providing a quick fix!
The elog is now happily running since two days without problems :)
I will get back to you in case anything else shows up. |
